Correct your 2018 tax return online

03 Oct 2019

The 2019 income tax campaign is coming to an end.

After completing their returns, each taxpayer received their tax notice this summer and paid the balance of the tax, if any, in September. However, if you realize that you have forgotten or made a mistake in your return, you can still correct it.

For remote filers, this correction can be made directly online until mid-December 2019. However, this service does not benefit from paper returns or returns made through a professional (EDI channel). It should be recalled that, from now on, the tax return must be filed electronically regardless of the taxpayer’s reference tax income, with some exceptions.

In practice:

the telecorrection service is accessible from the www.impots.gouv.fr website, in your particular space, but not on a smartphone or tablet.

In concrete terms, you can modify almost all the information (income, expenses, etc.), except that relating to your address, marital status or family status (marriage, family agreements, etc.). The elements relating to the tax on real estate wealth (IFI) set out in Annex 2042-IFI may also be corrected.

the withholding tax rate and, if applicable, the instalments calculated at the end of the amending declaration will not automatically appear in the section “Gérer mon prélèvement à la source“, but only after processing by the tax authorities.

After modification, you will receive a new tax notice indicating the final tax. In the event of a tax reduction, you will receive a refund of the overpayment. In the event of a tax increase, the amount to be paid and the payment deadline will be indicated on the notice.


If you filed your initial return on time, no penalty applies for telecorrection. On the other hand, reduced rate late payment interest may be claimed from you for amounts not declared on time.

After the online service has closed, you will have to make the claim, as other taxpayers do. A possible claim until December 31, 2021.
